Effect of latanoprost/timolol and dorzolamide/tiomolol on intraocular pressure after phacoemulsification surgery

AIM: To evalaute the effect of fixed-combination latanoprost 0.005%/timolol maleate 0.5% and dorzolamide hydrochloride 2%/timolol maleate 0.5% on postoperative intraocular pressure after phacoemulsification cataract surgery. METHODS: This study is a prospective, randomized, double-masked and placebo-controlled. The study included 90 eyes of 90 patients which were scheduled to have phacoemulsification surgery. Patients were randomly assigned preoperatively to 1 of 3 groups (30 eyes of 30 patients). Two hour before surgery, the patients received one drop latanoprost/timolol (group 1), dorzolamide/timolol (group 2) and placebo (group 3, control group). The IOPs were measured at preoperative and postoperative 4, 8, and 24 hours. RESULTS: The preoperative mean intraocular pressure was not statistically significant between both drug groups and control group. In group 1 and 2, the postoperative mean IOP [group1: (14.03±3.15)mmHg and group 2: (14.16±4.43)mmHg] at 24 hours were significantly lower than the control group [(16.93±3.70)mmHg, (P<0.05)]. In addition, the postoperative mean IOP of group 1 [(14.90±3.69)mmHg] at 8 hours was significantly lower than the control group [(17.70±3.89)mmHg, (P<0.05)], but there was no significant difference between group 2 [(16.16±5.23)mmHg] and control group at 8 hours (P>0.05). CONCLUSION: When compared with placebo, the use of preoperative fixed combination of latanoprost/ timolol and dorzolamide/timolol is an effective method for preventing intraocular pressure elevation in 24 hours after phacoemulsification surgery, but did not completely prevent IOP spikes.     

Additive effect of latanoprost and dorzolamide in patients with elevated intraocular pressure

Purpose : To evaluate the additive ocular hypotensive effect of latanoprost and dorzolamide in combination, on intraocular pressure reduction in patients with elevated intraocular pressure (IOP). Methods : Thirty patients with ocular hypertension or early capsular or primary open-angle glaucoma and elevated IOP were randomly assigned to two parallel treatment groups. The treatment period was twenty days. Fifteen patients (Group 1) received latanoprost once daily during the first ten days and, in addition, dorzolamide three times daily during the second ten days. Fifteen patients (Group 2) received dorzolamide three times daily during the first ten days and, in addition latanoprost, once daily during the second ten days. IOP was measured and conjunctival hyperemia was evaluated. Results : In Group 1, the mean IOP on day 0 was 26.8 mmHg; on day 10, 18.7 mmHg; and on day 20, 15.9 mmHg. In Group 2, the mean IOP on day 0 was 26.3 mmHg; on day 10, 21.2 mmHg; and on day 20, 16.1 mmHg. Both groups had clinically significant IOP- lowering effect on day 10 as compared with baseline day (30.2% and 19.4% respectively) (p < 0.01). When dorzolamide was added to latanoprost, the additional IOP reduction was 2.8 mmHg (15%) (p<0.01) compared with 5.1 mmHg (24.1%) (p<0.01when latanoprost was added to dorzolamide. No local serious adverse reactions were observed. A mild but statistically significant increase in conjunctival hyperemia was seen in latanoprost applied patients. Conclusions : The results showed that latanoprost and dorzolamide can be combined successfully to reduce IOP with their additive effects.     

Pain induced by phacoemulsification performed by residents using topical anesthesia.

BACKGROUND AND OBJECTIVE: To evaluate patient-reported pain induced by phacoemulsification performed by residents using topical anesthesia. PATIENTS AND METHODS: This prospective study comprised 81 eyes of 76 consecutive patients having phacoemulsification under topical anesthesia. Surgery was performed by an experienced surgeon (group 1; n=41 eyes) or by two residents (group 2; n=40 eyes). No sedation or intracameral anesthesia was used in either group. Eighty eyes had clear corneal phacoemulsification with foldable acrylic posterior chamber intraocular lens implantation. Patients were asked postoperatively to grade the pain they experienced during the procedure using a visual analog pain scale from 0 to 10. RESULTS: The median pain score for the overall pain was 1.59 +/- 1.43 (range: 0 to 6) in group 1 and 1.95 +/- 1.64 (range: 0 to 7) in group 2 (P = .291). The mean pain score for the maximum pain perceived was 2.39 +/- 1.86 (range: 0 to 7) in group 1 and 2.53 +/- 1.67 (range: 0 to 7) in group 2 (P = .734). There was no significant correlation between the duration of surgery and the overall pain score (r = 0.102, P = .365). CONCLUSION: Topical anesthesia had sufficient analgesic effects in selected patients undergoing phacoemulsification cataract surgery by resident surgeons. The pain felt during the operation was low and tolerable.     

Concomitant radiotherapy and hyperthermia for primary carcinoma of the vagina: a cohort study

OBJECTIVE: To evaluate the supplementary value of adding hyperthermia to radiotherapy in patients with primary vaginal cancer. STUDY DESIGN: Cohort of 44 patients diagnosed with primary vaginal cancer between 1990 and 2002 was assessed. Survival rates and median survival of patients with primary vaginal cancer undergoing radiotherapy with and without hyperthermia were compared. Hyperthermia was solely added to radiotherapy in case of a tumor size >4 cm in diameter for FIGO stage III disease. RESULTS: The calculated overall 5-year survival of primary vaginal cancer was 63%. In comparison to histologic high grade tumors, higher survival rates for histologic low grade tumors were calculated. For FIGO stage III of disease, the addition of hyperthermia to radiotherapy for tumors >4 cm in diameter resulted similar survival rates and median survival when compared to those achieved by radiotherapy as monotherapy in tumors of <4 cm in diameter. CONCLUSIONS: The addition of hyperthermia to radiotherapy might result in better survival rates in primary vaginal cancer for tumors >4 cm in diameter. The supplementary effect of hyperthermia to radiotherapy may be a feasible and beneficial approach in the treatment of vaginal cancer.     

Proteomic analysis and characterisation of human cervico-vaginal fluid proteins

AIM: Cervico-vaginal fluid (CVF) may provide insight into the biochemical pathways of human reproduction and parturition. The aim of this study was to establish a 2-D electrophoretic map of human CVF in healthy, pregnant women at term. METHODS: CVF was collected, concentrated and processed by routine 2-D polyacrylamide gel electrophoresis using pH 4-7-immobilised pH gradient strips and 8-16% gradient polyacrylamide gels. Imaged gels were analysed, yielding more than 400 proteins. A total of 157 proteins were common to all gels with a subgroup of the most abundant proteins being excised and characterised either by MALDI or by electrospray ion-trap mass spectrometry. RESULTS: Twenty-one proteins were successfully identified, yielding 15 different proteins. These included blood transport proteins (albumin and transthyretin); a structural protein (beta-actin); proteins involved in fatty acid metabolism (fatty acid-binding protein and acetyl-CoA-binding protein); a calcium-binding protein (annexin III); an anti-inflammatory cytokine (interleukin-1 receptor antagonist); proteinase inhibitors (alpha-1-antitrypsin, monocyte/neutrophil elastase inhibitor, squamous cell carcinoma antigen-1 and cystatin A); and enzymes involved in oxidative stress defence (thioredoxin, peroxiredoxin 2, glutathione S-transferase P and copper,zinc superoxide dismutase). CONCLUSION: CVF is a complex body fluid consisting of both endogenous and environmental proteins. The putative role of some of these proteins in the human reproductive tract is discussed.     

Validation of the prolapse quality of life questionnaire (P-QOL) in a Turkish population

OBJECTIVE: To validate the Turkish translated version of the prolapse quality of life questionnaire (P-QOL). STUDY DESIGN: After establishing the test-retest reliability and internal consistency in a pilot study, 310 patients were enrolled in the study and general and subscale scores of the questionnaires were calculated. All participants underwent the International Continence Society (ICS) prolapse score (POP-Q). RESULTS: One hundred and forty-five (49.7%) women were symptomatic and 147 (50.3%) were asymptomatic. The level of missing data ranged from 0 to 2.2%. For the test-retest reliability, Spearman's rho was from 0.91 to 1.00 for all domains (p<0.001). The severity of P-QOL was strongly correlated with the vaginal examination findings among the symptomatic group (p<0.001). Items correlated with the objective vaginal examination findings. The total and domain scores for P-QOL of symptomatic and asymptomatic women were found to be statistically significant (p<0.001). CONCLUSION: The Turkish translated version of the P-QOL is reliable, consistent and valid instrument for assessing symptom severity, impact on quality of life in women with uterovaginal prolapse. It is easy to understand may be easily administered and self-completed by the women.     

Laparoscopic hysterectomy with retroperitoneal uterine artery sealing using LigaSure™: Gazi hospital experience

OBJECTIVE: The aim of this study was to evaluate the efficacy and safety of laparoscopic hysterectomy by retroperitoneal sealing of the uterine arteries with LigaSure. METHODS: Laparoscopic hysterectomy by retroperitoneal uterine artery sealing with LigaSure was performed by four-puncture laparoscopy in 50 women with various indications for hysterectomy. The mean operation time, amount of intraoperative bleeding, drop in hemoglobin concentration, weight of removed uterus, major and minor per-post operative complications, and the rate of conversion to classical abdominal approach were analyzed prospectively. RESULTS: The mean operation time was 85 min (range 60-125 min). The mean weight of removed uterus was 180 g (range 60-650 g). There was one major complication; one patient had cystotomy due to difficulty in dissecting severe adhesions because of two previous cesarean sections that were repaired laparoscopically. Only one patient converted to laparotomy because of severe bowel adhesions due to rectovaginal endometriosis. All patients were discharged on the first postoperative day. No minor complications occurred. Hemoglobin decreased a mean of 0.4 g/dl (range 0.2-1.4 g/dl) by postoperative day 1. CONCLUSION: Laparoscopic hysterectomy by retroperitoneal uterine artery sealing with LigaSure is an effective, safe, and fast procedure with less intra operative bleeding, short operation time and hospital stay.     

A novel mutation in TRIM37 is associated with mulibrey nanism in a Turkish boy

Mulibrey nanism is a rare autosomal-recessive disorder characterized by prenatal onset severe growth retardation and pericardial constriction associated with abnormalities of muscle, liver, brain and eye. More than 80% of previously reported patients are of Finnish origin in whom a founder mutation in the TRIM37 gene have been described. We report on a 7-year-old Turkish boy who presented with classical phenotypic features of mulibrey nanism. Mutation screening of the TRIM37 gene revealed that the proband had a homozygous two base pair deletion, c.1894_1895delGA, resulting in a frame-shift and a premature termination codon. Our proband is one of the rare examples of mulibrey nanism outside Finland and extends the mutation spectrum in this disorder.     

Hypersensitivity to aeroallergens in patients with recurrent vulvovaginitis of undetermined etiology

AIM: Recent findings show that the vaginal mucosa can develop an allergic response to environmental allergens and there is a strong association between atopy and some recurrent vulvovaginal infections. In this study, we investigated prospectively the rate of atopy in patients with recurrent vulvovaginitis of undetermined etiology (RVV). MATERIAL AND METHODS: After being investigated by a gynecologist, 35 patients with RVV who were considered as undetermined etiology formed the study group. The control group consisted of 150 healthy females. Study and control groups were investigated for atopy by means of skin prick test for common aeroallergens. Associated allergic disease and familial atopy history of the subjects were recorded. RESULTS: The rate of atopy (11/35; 31.4% vs 9/150; 6%) was significantly higher (P < 0.001) in the study group than in the controls. Familial history of atopy was significantly more frequent in the study group than in the controls (10/35; 28.6% vs 8/150; 5.3%, P < 0.05). RVV in atopics is more associated with seasonal rhinitis than in nonatopics (5/11; 45.4% vs 2/24; 8.3%, P < 0.05). CONCLUSION: We concluded that a significant number of RVV is associated with atopy. Although the exact mechanism(s) of this relationship remains to be investigated atopy might be a causative and/or contributing factor in the pathogenesis of RVV.     

Renal angiomyolipoma with malignant transformation, simultaneous occurrence with malignity and other complex clinical situations

Renal angiomyolipoma is a benign kidney tumor, which is characterized by the presence of mature or immature fat tissue, thick-walled blood vessels, and smooth muscles. However, there is a rare possibility of transformation to a malignancy. This transformation could be toward sarcoma. And also angiomyolipoma could be associated with renal adenocarcinoma in the same kidney. The aim of this study is to show the association of angiomyolipoma with complex clinical situations such as malign transformation, simultaneous occurrence with adenocarcinoma, bilateral tumors with tuberous sclerosis or Wunderlich Syndrome. Findings of clinical presentation, pathological evaluation, urography, ultrasonography, and computerized tomography of 19 patients who were diagnosed angiomyolipoma in our clinic during 1994–2003 were examined retrospectively. Our records indicated that radical nephrectomy was performed in three cases of angiomyolipoma in which the differential diagnosis from adenocarcinoma could not be made and in another case of angiomyolipoma, which was associated with adenocarcinoma. Simple nephrectomy was performed in four symptomatic angiomyolipoma cases with tumor size larger than 4 cm and partial nephrectomy in another case. In one case, renal angiomyolipoma was associated with adenocarcinoma in the same kidney. In one case, post-operative recurrence of angiomyolipoma developed 7 months after nephrectomy. This patient was diagnosed low-grade leiomyosarcoma. Angiomyolipoma is regarded as a benign tumor of the kidney; however, it may also show aggressive behaviors and rarely transform to sarcoma. It may also exist in the same kidney along with adenocarcinoma or sarcoma.
